How Aspirin Works

Aspirin is a widely used antiplatelet drug that prevents blood clots by inhibiting the enzyme that makes platelets sticky. This helps reduce the risk of a stroke by keeping blood flowing smoothly through the arteries. It's often the first choice for those with low-risk TIAs.

Clopidogrel's Role

Clopidogrel is another antiplatelet medication that works by blocking a specific receptor on platelets, preventing them from clumping together. When used alongside aspirin, it provides an added layer of protection, particularly for patients with high-risk TIAs or minor strokes.
Aspirin and clopidogrel are antiplatelet medications used together to reduce the risk of stroke by preventing blood clots.

Combining Forces: Dual Antiplatelet Therapy

The combination of aspirin and clopidogrel is known as Dual Antiplatelet Therapy (DAPT). Research shows that DAPT is effective in reducing stroke risk when started promptly after a TIA or minor stroke. However, the therapy is typically limited to 21 days due to increased bleeding risk.

FAQs

Why combine aspirin and clopidogrel?

Together, they provide stronger prevention against blood clots.

Is aspirin alone enough?

For low-risk cases, yes, but high-risk patients may need both drugs.

What are the risks of DAPT?

Increased bleeding risk, limiting its use to short-term therapy.

How long is DAPT used?

Typically for 21 days after a TIA or minor stroke.

Key Takeaways

Aspirin and clopidogrel together can be powerful in stroke prevention but require careful management.
